Is there any limit to how much a shrub's growth can be restricted by pruning?
Purely for example, could a specimen of Viburnum x bodnantense ‘Dawn’, which can reach 10ft in height, be pruned so that it can be maintained at only 3ft in height?
Trouble with really restrictive pruning is that you can end up with a dumpy shapeless shrub and no flowers
Well, of course you could keep cutting it back to 3 ft, but you'd lose all the character of the plant.
If you're talking about real miniaturisation, then perhaps bonsai technques would be the way to go, but I'm way out of my depths there
Well, it can be cut back. I know someone who keeps their Dawn at about four feet, and rather columnar in shape. It does still flower, btu this is because it is pruned after flowering in the Spring. Later pruning might remove the flowering wood. If you plan to reduce yours, be prepared that you might lose the flowers for a year, until it recovers.
